Cloud security does not begin with controls—it begins with understanding responsibility.

Domain 3 of the CCSP curriculum focuses on securing the foundational layers of the cloud: compute, storage, networking, and virtualization. This domain shifts the learner’s mindset from traditional data-center thinking to cloud-native security design, where control is shared, infrastructure is abstracted, and scale is dynamic.

In the cloud, organizations no longer “own” the infrastructure—but they remain fully accountable for how it is used, configured, and protected. Domain 3 teaches how to secure what you can control, verify what you cannot, and govern what you depend on.

This domain emphasizes:

Unlike on-prem environments, cloud platforms evolve continuously. Security professionals must therefore focus on architecture, configuration, and assurance, rather than physical controls.

Domain 3 also reinforces a critical CCSP principle:

In the cloud, misconfiguration is the most common vulnerability—not missing technology.

By mastering this domain, professionals learn how to:

Ultimately, CCSP Domain 3 prepares you to trust the cloud without blindly trusting it—to build platforms that are secure by design, resilient by default, and continuously verified.

3.1 Comprehend Cloud Infrastructure and Platform Components

Cloud security begins with understanding what you are securing and where your responsibility starts and ends. Domain 3.1 breaks the cloud platform into foundational components—each with distinct security implications under the Shared Responsibility Model.

1. Physical Environment

Although cloud customers do not manage physical data centers, they remain accountable for due diligence and assurance.

Cloud providers are responsible for:

Customer responsibilities include:

CCSP Insight: Physical security is transferred, not eliminated. Trust is established through audits, not visibility.

2. Network and Communications

Cloud networking is software-defined, highly dynamic, and shared.

Key components:

Security considerations:

Exam Tip: Network isolation replaces physical separation in the cloud.

3. Compute

Compute represents the execution layer of cloud workloads.

Forms of compute:

Security responsibilities:

Shared responsibility varies:

CCSP Principle: The higher you go in abstraction, the more identity and configuration become your primary controls.

4. Virtualization

Virtualization is the core enabler of cloud computing and multi-tenancy.

Key elements:

Security concerns:

Mitigation strategies:

Exam Focus: Multi-tenancy increases efficiency—but also risk if isolation fails.

5. Storage

Cloud storage is elastic, replicated, and abstracted—but highly exposed if misconfigured.

Types of storage:

Security considerations:

Common risks:

CCSP Reality: Most cloud data breaches occur due to storage misconfiguration—not provider failure.

6. Management Plane

The management plane is the control center of the cloud—and the most sensitive layer.

Includes:

Security priorities:

Threats:

CCSP Golden Rule: Compromise of the management plane equals compromise of the entire cloud.

Key Takeaway

To secure the cloud, you must:

Cloud security is not about owning infrastructure—it is about governing it intelligently.

3.2 Design a Secure Data Center

Designing a secure data center—whether on-premises, colocation, or cloud-backed—is about architecting trust, resilience, and isolation from the ground up. CCSP Domain 3.2 focuses on how design decisions directly influence security posture, availability, and compliance.

1. Logical Design

Logical design defines how resources are isolated, accessed, and controlled, especially in multi-tenant environments.

Key aspects include:

In cloud environments, logical design replaces traditional physical boundaries. Isolation is achieved using:

Poor logical design can result in:

CCSP Insight: In the cloud, logical separation is your physical fence.

2. Physical Design

Physical design focuses on where and how infrastructure is located and protected.

Critical considerations include:

Organizations must decide:

Even in cloud models, customers must:

Exam Focus: Physical security responsibility may be delegated, but accountability cannot be outsourced.

3. Environmental Design

Environmental design ensures continuous operation of the data center under normal and adverse conditions.

Key elements include:

Multi-vendor pathway connectivity is critical to:

Environmental failures often cause:

CCSP Reality: Availability failures are often environmental—not cyber—incidents.

4. Designing for Resilience

Resilience is the ability to absorb failure and continue operating.

Resilient design includes:

In cloud environments, resilience is achieved through:

Resilience design directly supports:

CCSP Principle: Resilience is not an add-on—it is a design requirement.

Key Takeaway

Secure data center design is a multi-layered discipline combining:

Together, these ensure the data center can withstand attacks, failures, and disasters while maintaining trust and availability.

3.3 Analyze Risks Associated with Cloud Infrastructure and Platforms

Cloud risk analysis is not about fearing the cloud—it is about understanding how risk changes when control, visibility, and ownership are shared. CCSP Domain 3.3 equips professionals to identify, evaluate, and treat risks unique to cloud environments.

1. Risk Assessment in the Cloud

Risk assessment in cloud environments follows the same foundational principles as traditional security—but with expanded scope and dynamic variables.

The process includes:

Cloud-specific considerations include:

Unlike static data centers, cloud environments change rapidly, requiring continuous and automated risk assessment rather than periodic reviews.

CCSP Insight: In the cloud, risk is dynamic—assessment must be continuous, not annual.

2. Cloud Vulnerabilities, Threats, and Attacks

Cloud platforms introduce both inherited risks and new attack surfaces.

Common Cloud Vulnerabilities

Cloud-Specific Threats

Common Attacks

Many cloud breaches occur not due to provider failure, but due to customer misconfiguration or governance gaps.

Exam Focus: Cloud security failures are usually configuration failures, not technology failures.

3. Risk Mitigation Strategies

Risk mitigation in the cloud requires a layered, governance-driven approach.

Key mitigation strategies include:

Governance and Policy

Technical Controls

Operational Controls

Architectural Controls

CCSP Principle: Cloud risk is best mitigated through architecture, identity, and automation—not manual controls.

Key Takeaway

Effective cloud risk management requires:

Security professionals must shift from infrastructure-centric thinking to risk- and governance-centric decision-making in the cloud.

3.4 Plan and Implementation of Security Controls

Planning and implementing security controls in cloud environments requires precision, clarity of responsibility, and alignment with business risk. CCSP Domain 3.4 focuses on translating risk decisions into effective, enforceable, and auditable controls across physical, technical, and operational layers.

1. Physical and Environmental Protection

While physical and environmental controls are largely managed by cloud providers, organizations must ensure assurance, visibility, and contractual enforcement.

Key provider-controlled protections include:

Customer responsibilities include:

For hybrid or on-premises environments, organizations must directly implement:

CCSP Insight: Physical security may be outsourced—but risk ownership is not.

2. System, Storage, and Communication Protection

This layer focuses on protecting workloads, data, and data flows across the cloud infrastructure.

Key controls include:

System Protection

Storage Protection

Communication Protection

Exam Focus: Encryption alone is insufficient without strong access control and key management.

3. Identification, Authentication, and Authorization in Cloud Environments

Identity is the primary security control in the cloud.

Key identity practices include:

Authorization must be:

Cloud-native IAM enables fine-grained, scalable, and auditable access control, but misconfiguration can result in severe breaches.

CCSP Golden Rule: In the cloud, identity equals control.

4. Audit Mechanisms

Audit and monitoring provide visibility, accountability, and incident detection.

Key audit mechanisms include:

Effective auditing supports:

Cloud auditing must be:

CCSP Principle: If you can’t log it, you can’t secure it.

Key Takeaway

Successful security control implementation in the cloud requires:

Controls must be planned, implemented, tested, and continuously improved to remain effective in dynamic cloud environments.

3.5 Plan Business Continuity (BC) and Disaster Recovery (DR)

Planning for Business Continuity (BC) and Disaster Recovery (DR) in cloud environments is a strategic security responsibility, not merely a technical exercise. CCSP Domain 3.5 focuses on ensuring that organizations can sustain critical operations and recover IT services despite disruptions such as cyberattacks, system failures, natural disasters, or human error.

In cloud computing, BC and DR must be architected into the platform, aligned with business priorities, and clearly mapped to the Shared Responsibility Model.

1. Business Continuity (BC) and Disaster Recovery (DR) Strategy

A BC/DR strategy defines how the organization prepares for, responds to, and recovers from disruptive events.

Business Continuity (BC) addresses:

Disaster Recovery (DR) addresses:

In cloud environments, BC/DR strategies leverage:

CCSP Insight: Business continuity protects operations; disaster recovery restores technology.

2. Business Requirements: RTO, RPO, and Recovery Service Levels

BC/DR planning must be driven by business-defined recovery objectives, not purely technical constraints.

Recovery Time Objective (RTO)

Recovery Point Objective (RPO)

Recovery Service Level

In cloud models:

Exam Focus: RTO and RPO are business decisions implemented through technical controls.

3. Creation of the BC/DR Plan

The creation phase establishes structure, ownership, and preparedness.

Key activities include:

The plan must clearly identify:

CCSP Principle: A BC/DR plan without ownership is a document, not a strategy.

4. Implementation of the BC/DR Plan

Implementation translates strategy into operational capability.

Key implementation controls include:

Cloud-native capabilities enable:

CCSP Reality: Automation is essential for achieving aggressive RTO and RPO targets.

5. Testing and Maintenance of the BC/DR Plan

Testing validates whether BC/DR plans will function under real-world conditions.

Testing methods include:

Testing ensures:

Plans must be:

CCSP Golden Rule: An untested recovery plan is a false sense of security.

Key Takeaway

Effective BC/DR planning in the cloud ensures:

BC and DR are not optional safeguards—they are foundational elements of cloud trust and business survival.
